Abstract
Experimental measurements of the enhancement factors for mixtures of water vapor and CO2-free air have been made at -20, -10, and +70 �C. The results, coupled with previous experimental enhancement data, have been used to calculate the second interaction virial coefficients, Baw, for water vapor air mixtures from -50 to +90 �C. Within this temperature range, an error analysis shows that the uncertainties in Baw are between 6 and 10 percent. The calculated Baw values are used in deriving enhancement factors at 10 �C intervals for -50 < t < 90 �C, at varying pressure intervals from 0.25 to 100 bar. The associated uncertainties are shown as a function of pressure and temperature. The enhancement factors are extrapolated to -80 �C.
